No. 61/221,430, filedJun. 29, 2009 and U.S. Ser. No. 61/292,360, filed Jan. 5, 2010, each ofwhich is incorporated herein by reference in its entirety.

BACKGROUND OF INVENTION

Cancer cells rely primarily on glycolysis to generate cellular energyand biochemical intermediates for biosynthesis of lipids andnucleotides, while the majority of “normal” cells in adult tissuesutilize aerobic respiration. This fundamental difference in cellularmetabolism between cancer cells and normal cells, termed the WarburgEffect, has been exploited for diagnostic purposes, but has not yet beenexploited for therapeutic benefit.

Pyruvate kinase (PK) is a metabolic enzyme that convertsphosphoenolpyruvate to pyruvate during glycolysis. Four PK isoformsexist in mammals: the L and R isoforms are expressed in liver and redblood cells, the M1 isoform is expressed in most adult tissues, and theM2 isoform is a splice variant of M1 expressed during embryonicdevelopment. All tumor cells exclusively express the embryonic M2isoform. A well-known difference between the M1 and M2 isoforms of PK isthat M2 is a low-activity enzyme that relies on allosteric activation bythe upstream glycolytic intermediate, fructose-1,6-bisphosphate (FBP),whereas M1 is a constitutively active enzyme.

All tumor cells exclusively express the embryonic M2 isoform of pyruvatekinase, suggesting PKM2 as a potential target for cancer therapy. PKM2is also expressed in adipose tissue and activated T-cells. Thus, themodulation (e.g. inhibition or activation) of PKM2 may be effective inthe treatment of, e.g., obesity, diabetes, autoimmune conditions, andproliferation-dependent diseases, e.g., benign prostatic hyperplasia(BPH). Current inhibitors of pyruvate kinase are not selective, makingit difficult to treat disease related to pyruvate kinase function.

Furthermore, phosphotyrosine peptide binding to PKM2 leads to adissociation of FBP from PKM2 and conformational changes of PKM2 from anactive, tetrameric form to an inactive form. Compounds that bind to PKM2and lock the enzyme in the active confirmation will lead to the loss ofallosteric control of PKM2 needed for shunting biochemical intermediatesfrom glycolysis into biosynthesis of nucleotides and lipids. Thus, theactivation of PKM2 (i.e., activators of PKM2) can also inhibit thegrowth and proliferation of cancer cells, activated immune cells, andfat cells.

There is a continuing need for novel treatments of diseases such ascancer, diabetes, obesity, autoimmune conditions,proliferation-dependent diseases (e.g., BPH), and other diseases relatedto the function of pyruvate kinase (e.g., PKM2).

Methods of Evaluating Compounds

The compounds described herein can be evaluated for ability to modulatePKM2 (e.g., activate PKM2) by methods known in the art. In someembodiments, compounds described herein are evaluated for ability tomodulate PKM2 (e.g. activate PKM2) in serine deficient conditions. Insome embodiments, exemplary methods include contacting the compound witha cell-based assay which allows assessment of the ability to modulate(e.g., activate) PKM2. E.g., the candidate compound can be contactedwith a cell and measuring the consumption of oxygen or production oflactate. A change in cellular phosphoenolpyruvate, a change inglycerol-phosphate, a change in ribose or deoxyribose, a change in lipidsynthesis, or a change in glucose conversion to lipid or nucleic acidsor amino acids or protein can also be used to evaluate a compound forits ability to modulate PKM2 (e.g., activate PKM2). The evaluation couldalso include measuring a change in pyruvate or a determination of analteration in mitochondrial membrane potential, e.g., as measured byfluorescent potentiometric dyes.

The activity of the PKM enzyme measured in the screening/testing assaymay be measured by, e.g., monitoring the concentration of a substrate(e.g., ATP or NADH) present in the reaction mixture. Pyruvate, producedby the enzymatic activity of pyruvate kinase, is converted into lactateby lactate dehydrogenase, which requires the consumption of NADH(NADH→NAD+). Thus, the activity of PKM2 can be indirectly measured bymonitoring the consumption of NADH through, e.g., fluorescence assays.Additionally, the activity of the PKM2 enzyme can be directly monitoredby measuring the production of ATP, as ATP is produced whenphosphoenolpyruvate is converted to pyruvate. Methods for monitoring theamount of substrate in a reaction mixture include, e.g., absorbance,fluorescence, Raman scattering, phosphorescence, luminescence,luciferase assays, and radioactivity.

The screening procedure requires the presence of specific components inthe reaction mixture. Components utilized in the assay include, e.g., anucleoside diphosphate (e.g., ADP), phosphoenolpyruvate, NADH, lactatedehydrogenase, FBP, a reducing agent (e.g., dithiothreitol), a detergent(e.g., Brij 35), glycerol, and a solvent (e.g., DMSO). Exemplaryreaction conditions are found in Table 1.

In some embodiments, a compound such as a compound described herein, canbe evaluated in a cellular/ex vivo assay. For example, a cell is treatedwith a compound described herein (i.e., a PKM2 activator), and thecompound is evaluated, for example for its ability to enter the cell andbind to PKM2, inducing an activated conformation of PKM2. The excessunbound compound can then be washed away with PBS, and the cells lysed,for example, by snap-freezing on dry ice, followed by addition of adetergent-containing lysis buffer. The lysate, in which activated PKM2remains intact, can then be removed and added to a chemical cocktailincluding the chemicals necessary to measure pyruvate kinase activity.The assay can be coupled to another assay such as an assay that iscoupled to the LDHa enzyme. The amount of pyruvate kinase activity thatis measured can then be normalized to the total protein content in thelysate, and related to the concentration of PKM2 activator that wasadded to the cell. This can allow an AC₅₀ (concentration at which PKM2is activated 50%) value to be derived. The total fold-increase inactivity over mock-treated cells can also be calculated, and the“maximum level of activation” can be used to distinguish betweencompounds that fully activate PKM2 and compounds that can only partiallyactivate PKM2. In the case of measuring PKM2 activity from tissue (forexample, in a cell tumor), animals harboring the tissue/tumor ofinterest can be dosed with a compound. After a specified period of timein which exposure has been achieved in the target tissue/tumor ofinterest, the tissue/tumor can then be harvested from the animal,snap-frozen, and then lysed and homogenized. The amount of pyruvatekinase activity in this lysate can then be quantitated as describedabove.

PKM1 and PKM2 for use in the screening/testing methods described hereinmay be produced by any method known in the art for expression ofrecombinant proteins. For example, nucleic acids that encode the desiredpolypeptide may be introduced into various cell types or cell-freesystems for expression. Eukaryotic (e.g., COS, HEK293T, CHO, and NIHcell lines) and prokaryotic (e.g., E. coli) expression systems may begenerated in which a PKM sequence is introduced into a plasmid or othervector, which is then used to transform living cells. Constructs inwhich the PKM cDNA contains the entire open reading frame, orbiologically active fragment thereof, are inserted in the correctorientation into an expression plasmid and may be used for proteinexpression. Prokaryotic and eukaryotic expression systems allow for theexpression and recovery of fusion proteins in which the PKM protein iscovalently linked to a tag molecule on either the amino terminal orcarboxy terminal side, which facilitates identification and/orpurification. Examples of tags that can be used include hexahistidine,HA, FLAG, and c-myc epitope tags. An enzymatic or chemical cleavage sitecan be engineered between the PKM protein and the tag molecule so thatthe tag can be removed following purification.

Compounds useful as PKM2 activators are those demonstrate specificityand activation of PKM2 enzyme in the absence of FBP to a level greaterthan that of 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80,85, 90, 95, 99, or 100% in the presence of FBP. Furthermore, compoundscan be evaluated in the presence or absence of a phosphotyrosinepeptide. Phosphotyrosine peptide binding to PKM2 leads to a dissociationof FBP from PKM2 and conformational changes of PKM2 from an active,tetrameric form to an inactive form. Compounds that bind to PKM2 andlock the enzyme in the active confirmation even in the presence of aphosphotyrosine peptide will lead to the loss of allosteric control ofPKM2 needed for shunting the biochemical intermediates from glycolysisinto biosynthesis of other intermediates. This, in turn, will lead toinhibition of growth of cancer cells, activated immune cells and fatcells.

Exemplary cancertreatments include, for example: chemotherapy, targeted therapies suchas antibody therapies, immunotherapy, and hormonal therapy. Examples ofeach of these treatments are provided below.

Chemotherapy

In some embodiments, a compound described herein is administered withone or morechemotherapies. Chemotherapy is the treatment of cancer withdrugs that can destroy cancer cells. “Chemotherapy” usually refers tocytotoxic drugs which affect rapidly dividing cells in general, incontrast with targeted therapy. Chemotherapy drugs interfere with celldivision in various possible ways, e.g., with the duplication of DNA orthe separation of newly formed chromosomes. Most forms of chemotherapytarget all rapidly dividing cells and are not specific for cancer cells,although some degree of specificity may come from the inability of manycancer cells to repair DNA damage, while normal cells generally can.

Examples of chemotherapeutic agents used in cancer therapy include, forexample, antimetabolites (e.g., folic acid, purine, and pyrimidinederivatives) and alkylating agents (e.g., nitrogen mustards,nitrosoureas, platinum, alkyl sulfonates, hydrazines, triazenes,aziridines, spindle poison, cytotoxic agents, toposimerase inhibitorsand others). Exemplary agents include Aclarubicin, Actinomycin,Alitretinon, Altretamine, Aminopterin, Aminolevulinic acid, Amrubicin,Amsacrine, Anagrelide, Arsenic trioxide, Asparaginase, Atrasentan,Belotecan, Bexarotene, endamustine, Bleomycin, Bortezomib, Busulfan,Camptothecin, Capecitabine, Carboplatin, Carboquone, Carmofur,Carmustine, Celecoxib, Chlorambucil, Chlormethine, Cisplatin,Cladribine, Clofarabine, Crisantaspase, Cyclophosphamide, Cytarabine,Dacarbazine, Dactinomycin, Daunorubicin, Decitabine, Demecolcine,Docetaxel, Doxorubicin, Efaproxiral, Elesclomol, Elsamitrucin,Enocitabine, Epirubicin, Estramustine, Etoglucid, Etoposide,Floxuridine, Fludarabine, Fluorouracil (5FU), Fotemustine, Gemcitabine,Gliadel implants, Hydroxycarbamide, Hydroxyurea, Idarubicin, Ifosfamide,Irinotecan, Irofulven, Ixabepilone, Larotaxel, Leucovorin, Liposomaldoxorubicin, Liposomal daunorubicin, Lonidamine, Lomustine, Lucanthone,Mannosulfan, Masoprocol, Melphalan, Mercaptopurine, Mesna, Methotrexate,Methyl aminolevulinate, Mitobronitol, Mitoguazone, Mitotane, Mitomycin,Mitoxantrone, Nedaplatin, Nimustine, Oblimersen, Omacetaxine, Ortataxel,Oxaliplatin, Paclitaxel, Pegaspargase, Pemetrexed, Pentostatin,Pirarubicin, Pixantrone, Plicamycin, Porfimer sodium, Prednimustine,Procarbazine, Raltitrexed, Ranimustine, Rubitecan, Sapacitabine,Semustine, Sitimagene ceradenovec, Satraplatin, Streptozocin,Talaporfin, Tegafur-uracil, Temoporfin, Temozolomide, Teniposide,Tesetaxel, Testolactone, Tetranitrate, Thiotepa, Tiazofurin, Tioguanine,Tipifarnib, Topotecan, Trabectedin, Triaziquone, Triethylenemelamine,Triplatin, Tretinoin, Treosulfan, Trofosfamide, Uramustine, Valrubicin,Verteporfin, Vinblastine, Vincristine, Vindesine, Vinflunine,Vinorelbine, Vorinostat, Zorubicin, and other cytostatic or cytotoxicagents described herein.

Because some drugs work better together than alone, two or more drugsare often given at the same time. Often, two or more chemotherapy agentsare used as combination chemotherapy. In some embodiments, thechemotherapy agents (including combination chemotherapy) can be used incombination with a compound described herein.

Targeted Therapy

In some embodiments, a compound described herein is administered withone or more targeted therapies. Targeted therapy constitutes the use ofagents specific for the deregulated proteins of cancer cells. Smallmolecule targeted therapy drugs are generally inhibitors of enzymaticdomains on mutated, overexpressed, or otherwise critical proteins withinthe cancer cell. Prominent examples are the tyrosine kinase inhibitorssuch as Axitinib, Bosutinib, Cediranib, dasatinib, erlotinib, imatinib,gefitinib, lapatinib, Lestaurtinib, Nilotinib, Semaxanib, Sorafenib,Sunitinib, and Vandetanib, and also cyclin-dependent kinase inhibitorssuch as Alvocidib and Seliciclib. Monoclonal antibody therapy is anotherstrategy in which the therapeutic agent is an antibody whichspecifically binds to a protein on the surface of the cancer cells.Examples include the anti-HER2/neu antibody trastuzumab (HERCEPTIN®)typically used in breast cancer, and the anti-CD20 antibody rituximaband Tositumomab typically used in a variety of B-cell malignancies.Other exemplary antibodies include Cetuximab, Panitumumab, Trastuzumab,Alemtuzumab, Bevacizumab, Edrecolomab, and Gemtuzumab. Exemplary fusionproteins include Aflibercept and Denileukin diftitox. In someembodiments, the targeted therapy can be used in combination with acompound described herein.

Targeted therapy can also involve small peptides as “homing devices”which can bind to cell surface receptors or affected extracellularmatrix surrounding the tumor. Radionuclides which are attached to thesepeptides (e.g., RGDs) eventually kill the cancer cell if the nuclidedecays in the vicinity of the cell. An example of such therapy includesBEXXAR®.

Immunotherapy

In some embodiments, a compound described herein is administered withone or more immunotherapies. Cancer immunotherapy refers to a diverseset of therapeutic strategies designed to induce the patient's ownimmune system to fight the tumor. Contemporary methods for generating animmune response against tumors include intravesicular BCG immunotherapyfor superficial bladder cancer, and use of interferons and othercytokines to induce an immune response in renal cell carcinoma andmelanoma patients.

Allogeneic hematopoietic stem cell transplantation can be considered aform of immunotherapy, since the donor's immune cells will often attackthe tumor in a graft-versus-tumor effect. In some embodiments, theimmunotherapy agents can be used in combination with a compounddescribed herein.

Hormonal Therapy

In some embodiments, a compound described herein is administered withone or more hormonal therapies. The growth of some cancers can beinhibited by providing or blocking certain hormones. Common examples ofhormone-sensitive tumors include certain types of breast and prostatecancers. Removing or blocking estrogen or testosterone is often animportant additional treatment. In certain cancers, administration ofhormone agonists, such as progestogens may be therapeuticallybeneficial. In some embodiments, the hormonal therapy agents can be usedin combination with a compound described herein.

Obesity and Fat Disorders

A compound or composition described herein can be used to treat orprevent obesity, e.g., in a human subject, e.g. a child or adultsubject. “Obesity” refers to a condition in which a subject has a bodymass index of greater than or equal to 30. Many compounds describedherein can be used to treat or prevent an over-weight condition.“Over-weight” refers to a condition in which a subject has a body massindex of greater or equal to 25.0. The body mass index (BMI) and otherdefinitions are according to the “NIH Clinical Guidelines on theIdentification and Evaluation, and Treatment of Overweight and Obesityin Adults” (1998). Treatment with the compound may be in an amounteffective to alter the weight of the subject, e.g., by at least 2, 5, 7,10, 12, 15, 20, 25, 30, 25, 40, 45, 50, or 55%. Treatment with acompound may be in an amount effective to reduce the body mass index ofthe subject, e.g., to less than 30, 28, 27, 25, 22, 20, or 18. Thecompounds can be used to treat or prevent aberrant or inappropriateweight gain, metabolic rate, or fat deposition, e.g., anorexia, bulimia,obesity, diabetes, or hyperlipidemia (e.g., elevated triglyceridesand/or elevated cholesterol), as well as disorders of fat or lipidmetabolism.

A compound or composition described herein can be administered to treatobesity associated with Prader-Willi Syndrome (PWS). PWS is a geneticdisorder associated with obesity (e.g., morbid obesity).

A compound or composition described herein can be used to reduce bodyfat, prevent increased body fat, reduce cholesterol (e.g., totalcholesterol and/or ratios of total cholesterol to HDL cholesterol),and/or reduce appetite in individuals having PWS associated obesity,and/or reduce comorbidities such as diabetes, cardiovascular disease,and stroke.

Synthesis of N4-aryl/heteroaryl Piperazine Analogues with SubstitutedPhenyl Central Ring.

General Procedure for Compound 94: Nitrogen was purged through a stirredsolution of arylbromide (93, 2.15 mmol) in 1,4-dioxane (20 ml) at roomtemperature for 30 min. BINAP (0.134 g, 0.215 mmol), palladium acetate(0.0096 g, 0.043 mmol) and cesium carbonate (1.40 g, 4.3 mmol) wereadded to the reaction mixture and the nitrogen purging was continued foranother 20 min. and finally N-Boc piperazine (85, 0.4 g, 2.15 mmol) wasadded and stirred at 100° C. overnight under nitrogen atmosphere. Aftercompletion of the reaction (monitored by TLC), the reaction mixture wasconcentrated under vacuum. The residue was dissolved in water, extractedwith ethyl acetate (3×50 ml). Combined organic extracts were washed withbrine (20 ml), dried over anhydrous Sodium sulfate, filtered andconcentrated under reduced pressure. The crude product was then purifiedby column chromatography (60-120 silica gel) using 10% ethylacetate-hexane to yield compound (94) (40-60%).

General Procedure for Compound (95): N¹-Boc-N⁴-arylpiperazine (94, 1.075mmol) was taken into a round bottomed flask and was added methanolic-HCl(20 ml, 20%) which resulted in formation of a homogeneous solution andwas stirred for 1 h at room temperature. After completion of thereaction (monitored by TLC), the solvent was removed under vacuum. Thecrude product was washed with ethyl acetate repeatedly and then driedwell to obtain hydrochloride salt (95) (90%) as a white solid.

General Procedure for Compound 97: To a solution of amine (96, 30.16mmol) in a 1:1 mixture of DCM-pyridine (50:50 ml) was addedquinoline-8-sulfonyl chloride (89, 8.24 g, 36.19 mmol) under nitrogenatmosphere. The resultant solution was stirred overnight at roomtemperature. On completion of the reaction (monitored by TLC), thereaction mixture was diluted with dichloromethane (150 ml), washed withwater (3×50 ml), 1N HCl solution (3×50 ml) and brine (50 ml. Thecombined organic extracts were dried over anhydrous sodium sulfate,filtered and concentrated under vacuum. Crude product was co-distilledwith toluene to remove the remnants of pyridine and dried to yieldsulfonamide (97) (70-90%) as an off-white solid and was used as such forthe next step without further purification.

General Procedure for Compounds 98a-l: To a stirred solution of thecarboxylic acid (97, 0.61 mmol) in DMF at 0° C. under nitrogenatmosphere, EDCI (0.129 gm, 0.671 mmol), HOBt (0.91 gm, 0.671 mmol) andDIPEA (0.31 ml, 1.83 mmol) were added and the resultant solution wasstirred at room temperature for 30 min. Amine hydrochloride (95, 0.61mmol) was then added at 0° C. and stirred overnight at room temperature.After completion of the reaction (monitored by TLC), the reactionmixture was poured into 1.0 M HCl and extracted with EtOAc. The organiclayer was washed with saturated NaHCO₃ solution, dried over NaSO₄ andfiltered. The solvent was removed by rotary evaporation and the productwas isolated by chromatography on silica gel (60-120 silica gel, 2%MeOH-DCM) or preparative HPLC to yield amide (98a-l) (40-60%) as anoff-white solid.

Synthesis of Piperazine Derivatives with 3-methyl, 2-methyl, 3-fluoro,3-chloro, 3-hydroxy or 3-methoxy Substituted Phenyl Rings

General procedure for the synthesis of sulfonamide 118: To a stirredsolution of amine 7 (30.3 mmol) under nitrogen atmosphere was addedpyridine (50 ml) at 0° C. and stirred for 10 min. Quinoline-8-sulfonylchloride 89 (8.94 gm, 39.4 mmol) was then added to the reaction mixtureat the same temperature. The resulting mixture was stirred for 16 hr atRT. After completion of the reaction, the solvent was removed under lowpressure. The traces of pyridine were removed by co-distillation withtoluene. Diethylether was added to the resulting residue, and the solidproduct was filtered out and air-dried. The resulting crude product (8.0gm, 74%) was then to the next step without further purification.

General procedure for the synthesis of sulfonamide 119: EDCI (3.8 g,19.8 mmol) and HOBT (2.67 g, 19.8 mmol) were added to a stirred solutionof the acid 118 (19.8 mmol) in anhydrous DMF. The temperature of themixture was reduced to 0° C., at which time DIPEA (11 ml, 59.45 mmol)was added under nitrogen atmosphere and the resultant solution (orsuspension) was stirred at room temperature for 30 min. Boc-piperazine(3.68 g, 19.8 mmol) was then added at 0° C. The reaction mixture wasthen brought to room temperature and stirred overnight. After completionof the reaction, the reaction mixture was diluted with water andextracted with ethyl acetate (3×70 ml). The organic layer was washedwith water (3×50 ml), dried over anhydrous sodium sulfate, filtered andconcentrated over the rotary evaporator to get the crude product. Crudeproduct was purified by column chromatography (60-120 silica gel, 2%MeOH-DCM) to get pure product, Boc-119 (81%) as an off-white solid,which was subjected to the treatment with methanolic HCl (100 ml) for 2hr at RT. After the complete cleavage of Boc-group, the solvent wasremoved under low pressure, to give the crude product as an HCl salt.The aqueous solution of the salt was washed with diethylether andbasified with NaHCO₃ (pH 10). The desired product was then partitionedinto ethyl acetate, dried with anhydrous Na₂SO₄ and the solvent removedunder low pressure to get the free amine 119 as off white solid (95%).

General procedure for the synthesis of amides 120a-cu: EDCI (48 mg,0.2525 mmol) and HOBT (34 mg, 0.2525 mmol) were added to a stirredsolution of the Ar—COOH (0.2525 mmol) in anhydrous DMF. The temperatureof the mixture was reduced to 0° C., at which time DIPEA (139 al, 0.7575mmol) was added under nitrogen atmosphere and the resultant solution (orsuspension) was stirred at room temperature for 30 min. Amine 119 (100mg, 0.2525 mmol) was then added at 0° C. The reaction mixture was thenbrought to room temperature and stirred overnight. After completion ofthe reaction, the reaction mixture was diluted with water and extractedwith ethyl acetate (3×15 ml). The organic layer was washed with water(3×10 ml), dried over anhydrous sodium sulfate, filtered andconcentrated over the rotary evaporator to get the crude product. Crudeproduct was purified by either by silica column chromatography orpreparative HPLC to obtain the pure products in 52-68% yields.

Synthesis of Piperazine Derivatives with 3-trifluoromethyl or3-trifluoromethoxy Substituted Phenyl Rings

General procedure for the synthesis of sulfonamide 122: To a stirredsolution of amine 121 (30.3 mmol) in DMF (20 ml per gm) under nitrogenatmosphere was added sodium hydride (90.9 mmol) portion-wise at 0° C.and stirred for 10 min at RT. Quinoline-8-sulfonyl chloride 89 (8.94 gm,39.4 mmol) was then added to the reaction mixture at 0° C. The resultingmixture was stirred for further 30 min at RT. After completion of thereaction, most of the solvent was removed under low pressure. Theresidue was diluted with ice water-EtOAc mixture and the pH was broughtto 7.0 using saturated solution of NaH₂PO₄. The product was thenextracted in EtOAc, washed with water and brine, dried over sodiumsulphate and the solvent removed under low pressure. The resulting crudeproduct (80%) was then to the next step without further purification.

General procedure for the synthesis of hydrolysis product 123: To astirred solution of sulfonamide 122 (22.4 mmol) in THF:H₂O (1:1) undernitrogen atmosphere was added solid LiOH (9.4 gm, 224 mmol) at RT. Thesolution was then refluxed for 6 hr. After completion of the reaction,the reaction mixture was washed with ethyl acetate (2×100 ml) to removenon polar impurities.
